Description

[Technical Field]

[0001] This invention relates to a mop cover for a window mop used as a manual cleaning tool for cleaning window glass, and in particular to a mop cover for a window mop that is placed over the horizontal rod-shaped head portion at the tip of a T-shaped support member and cleaned by gripping the vertical rod-shaped handle portion at the base end of the support member. [Background technology]

[0002] Window mops are used when manually cleaning building windows. As an example, as described in Patent Document 1 (JP 2012-40286 A), a mop cover is a bag-shaped structure with both ends and one half of the side closed, with an opening in the other half of the side. The mop cover is attached by inserting the horizontal rod-shaped head of the support member through the opening and closing the opening. A hook-and-loop fastener or hooks are used to close the opening. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-40286 Summary of the Invention [Problem to be solved by the invention]

[0004] However, window mops like those described in Patent Document 1 have the problem of leaving areas of the window glass near the window frame uncleaned. The reason for this is as follows: When the head is attached to the mop cover, the cleaning surface of the mop becomes the side of a roughly cylindrical cylinder. Schematically speaking, the window glass (vertical surface) is cleaned with the side (circumferential part) of the cylindrical mop, but the mop cleaning surface does not come into contact with the area near the intersection of the window glass (vertical surface) and the window frame (horizontal surface) (see Figure 6-a), resulting in insufficient cleaning and leaving areas uncleaned.

[0005] The present invention has been made in view of the above circumstances, and aims to provide a mop cover for a window mop that can clean the window glass up to the boundary between the window glass and the window frame and can clean efficiently. [Means for solving the problem]

[0006] The invention made to solve the above problem is a mop cover that has a cover body that is approximately rectangular and bag-shaped, extends in the longitudinal direction, and has an opening that opens and closes in the width direction perpendicular to the longitudinal direction, and is used by removably inserting the head portion of a T-shaped support member that has a rod-shaped handle portion extending vertically from the center of the rod-shaped head portion extending horizontally into the opening.

[0007] The mop cover of the present invention comprises a closing means for closing the opening when the head portion of the support member is inserted into the opening, and an inner wall cloth whose both widthwise ends are fixed to the inner wall of the cover body by a first fixing line extending in the longitudinal direction, and is characterized in that when the head portion is inserted, there is a gap between the inner wall cloth and the folded portion inside the cover body.

[0008] The mop cover of the present invention has an inner wall fabric on the inside, so when the handle head is inserted and secured into the mop cover, the cylindrical shape of the head is not reflected in the mop cover, resulting in a V-shaped cross section of the mop cleaning part. By using the tip of this V-shape, it is possible to clean windows right up to the window frame (Figure 6-b). Furthermore, unlike a typical mop cover with a round cross section, the area of ​​contact between the mop cover and the object being cleaned is wider when sliding, allowing for quicker cleaning.

[0009] In the mop cover of the present invention, it is preferable that the inner wall cloth is fixed to the cover body by a second fixing line extending in the longitudinal direction and widthwise inward of the first fixing line. With this configuration, when a mop head is inserted into the mop cover, the second fixing lines of the inner wall cloth move closer to each other, causing the inner wall cloth to exert a force pulling the body inward, thereby more firmly maintaining the V-shaped shape of the mop cover.

[0010] Furthermore, it is also preferable that the closing means uses a hook and loop fastener, and has a first hook and a second hook and loop fastener provided at symmetrical positions on either side of the opening on the long side of the opening, the first hook and loop fastener being made of a sheet piece having one of hooks or loops on both sides and a base end edge fixed to one long side of the opening, the second hook and loop fastener being made of two sheet pieces having the other of hooks or loops on opposing sides and a base end edge fixed to the other long side of the opening so as to be openable and closable like a booklet, and the first hook and loop fastener is sandwiched between the two sheet pieces of the second hook and loop fastener to form a mop cover in which the first hook and loop fastener is fixed to the second hook and loop fastener. Fixation using hook and loop fasteners can loosen or come off depending on the usage situation, but this configuration makes the fixation stronger.

[0011] Preferably, two sets of the closing means are provided along the long side direction of the opening, and the first and second hook-and-loop fasteners of the two sets of closing means are positioned symmetrically about the center of the opening. This distributes the direction of the force applied to the closing means during cleaning, making it even more difficult for the fastening to loosen.

[0012] More preferably, the cover body is made of pile fabric and another fabric made of woven or knitted fabric layered on top of it. The double-layered structure of pile fabric and another fabric layered on top of it increases the durability of the body. Note that durability here includes durability against the force applied when the pile fabric is brought into contact with and slid over the surface of the object to be cleaned, as well as durability that allows the mop cover to be used for a long period of time. [Effects of the Invention]

[0013] As described above, by using the mop cover of the present invention on a window mop, it is possible to clean the window glass right up to the boundary with the window frame. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015]

[0023] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Figure 1 shows a mop cover 1 according to one embodiment of the present invention. In the following description, the left-right direction in Figure 1 may be simply referred to as the "longitudinal direction," the up-down direction in Figure 1 may be simply referred to as the "width direction," and the depth direction in Figure 1 may be simply referred to as the "depth direction."

[0016] As shown in Figures 1 to 3, the mop cover 1 is in the shape of a substantially rectangular bag and includes a cover body 15 having an opening 3 extending in the longitudinal direction, a pair of closing means 6, 6 for closing the opening 3, and an inner wall fabric 2 fixed to the inner wall of the cover body 15. As shown in Figure 3, the mop cover 1 is used by detachably inserting the head portion 16 of a T-shaped support member 18 having a rod-shaped handle portion 17 extending vertically (up and down in Figure 3) from the center of the rod-shaped head portion 16 extending horizontally (left and right in Figure 3) into the opening 3.

[0017] The cover body 15 is formed by overlapping a reinforcing lining 14 on the backside of a rectangular pile fabric 13, folding the ribbon-like fabric 11 in half at the center in the width direction over a pair of opposing long sides of the rectangle and sewing it, then folding it in half at a folded-back part 151 extending in the longitudinal direction (left and right direction in Fig. 1), and sewing (closing) both ends in the longitudinal direction. In Fig. 1, reference numeral 154 indicates the sewn part, and 155 indicates the part woven inside.

[0018] In this example, polyester is used for the pile fabric, and a mesh fabric of polyester fibers with a fineness of over 100 dtex is used for the lining. However, there are no limitations on the fiber materials used for the pile fabric or lining. Natural fibers such as cotton can be used, and synthetic fibers such as nylon, acrylic, and polylactic acid fibers can also be used. Known materials can be used, and multiple fiber materials can also be mixed. Pile fabric is preferably used for the purpose of this invention, but woven, knitted, and nonwoven fabrics other than pile fabric can also be used.

[0019] 2, the opening 3 is provided facing the folded portion 151 of the cover body 15 and extending in the longitudinal direction of the cover body 15 in parallel with the folded portion 151. The opening 3 is formed by not meeting a pair of long sides of the cover body 15, and the pair of long sides form rim portions 152, 153 consisting of a pair of edges facing each other in the width direction of the opening 3.

[0020] As shown in FIG. 1, the closing means 6 has a first surface fastener 4 and a second surface fastener 5 that face each other in the width direction of the opening 3 with the opening 3 interposed therebetween.

[0021] The first hook-and-loop fastener 4 is formed by sewing the base end edge of a sheet piece having either a hook or a loop (hook in the example of Figure 1) on both sides to the edge portion 152 that forms one of the widthwise edges of the opening 3.

[0022] The second surface fastener 5 has two sheet pieces 5a, 5b whose tip ends are provided in a booklet-like manner so as to be able to be opened and closed. The two sheet pieces 5a, 5b have the other of a hook or a loop (a loop in the illustrated example) on their opposing surfaces. The base end edges of the sheet pieces 5a, 5b are fixed to a rim portion 152 (153) that forms the other edge of the width direction of the opening 3.

[0023] The closing means 6 is closed by clamping the first surface fastener 4 between the two sheet pieces 5a, 5b of the second surface fastener 5 and fixing the first surface fastener 4 to the second surface fastener 5. When the opening 3 is closed by the closing means 6 with the head portion 16 of the support member 18 inserted into the opening 3, the head portion 16 is firmly fixed inside the cover body 15.

[0024] The inner wall cloth 2 is sewn (fixed) to the inside of the cover body. In this embodiment, the inner wall cloth 2 is made of the same fabric material as the lining 14 of the cover body 15. The size of the inner wall cloth 2 is smaller than the pile fabric 13 and the lining 14 both lengthwise and widthwise. The two long sides of the inner wall cloth 2 are aligned with the long sides of the pile fabric 13 and the lining 14, respectively, and the ribbon-like fabric 11 is attached and sewn to form the edges 152, 153 of the opening 3.

[0025] In this embodiment, the first fixing line 12a is the same as the sewing location of the ribbon-like fabric 11. In other words, when the ribbon-like fabric is sewn to the rim portions 152, 153, the inner wall cloth 2, along with the pile fabric 13 and lining 14, is covered with the ribbon-like fabric 11 and sewn to the rim portions 152, 153. Since the inner wall cloth 2 is shorter in width than the pile fabric 13 and lining 14, sewing both ends (long sides) in the width direction to the pile fabric 13 and lining 14 in this way separates the center in the width direction from the lining 14. In this way, a gap 8 is formed between the inner wall cloth 2 and the folded-back portion 151 of the cover body 15.

[0026] This prevents the head part 16 of the support member 18 from penetrating deep into the cover body 15, and prevents the folded part of the cover body 15 from expanding cylindrically, in other words, the folded part can maintain its triangular pointed shape, so that the folded part 151 side of the cover body 15 can be easily inserted into the gap between the window glass and the window frame.

[0027] 1, the inner wall cloth 2 has its short sides (both longitudinal sides) 21, 21 not sewn to the cover body 15, which allows it to bend in the depth direction. In this embodiment, the inner wall cloth 2 is further sewn to the cover body 15 by a pair of second fixing lines 12b, 12b extending in the longitudinal direction and located widthwise inward of the first fixing lines.

[0028] As a result, when the head portion 16 shallowly abuts the interior wall cloth 2, a gap S is formed between the head portion 16 and the second fixing lines 12b of the interior wall cloth 2, as shown in Figure 4. At this time, the distance between the pair of second fixing lines is D1. When the opening 3 is closed and the head portion 16 penetrates deep into the mop cover 1, the gap S disappears and the portion of the interior wall cloth 2 between the second fixing lines 12b, 12b is not attached to the head portion 16, so the distance D2 between the pair of second fixing lines 12b, 12b becomes shorter than D1. As a result, as shown in Figure 5, the gap 8 is small and the folded portion 151 of the mop cover 1 becomes more pointed, making it easier to penetrate into the gap between the window glass and the window frame.

[0029] The mop cover 1 introduced in this example is sized to fit a mop head that is approximately 35 cm wide and 2.8 cm in diameter. Mop covers of any size can be manufactured by adjusting the size of the material to match the size of the mop head.

[0030] Figure 3 shows the state in which the head portion 16 of the support member is inserted into the mop cover 1 of the present invention. It is fixed with hook-and-loop fasteners at two locations.

[0031] The AA and BB cross-sectional views of Figure 3 are shown in Figures 4 and 5. It is important to note that the center of the inner wall fabric 2 does not touch the inside of the mop cover at all. With this configuration, even when the head 16 is attached to the mop cover 1 of the present invention, the cylindrical shape of the head 16 is not reflected in the mop cover 1, and the cross-section of the mop cover becomes "V" shaped, as shown in Figures 4 and 5. The V-shape is more firmly held in the areas secured with hook-and-loop fasteners, as shown in Figure 5. Using these V-shaped tips allows the mop cover 1 to clean right up to the edge of the window frame, even at the joint between the window glass and the window frame. Furthermore, by providing a second securing line in addition to the first securing line, the V-shaped cross-section of the mop cover 1 becomes even narrower, as described above, allowing the mop cover 1 to clean even right up to the edge of the window frame.

[0032] This situation is shown in Figure 6. (a) shows the cleaning state of the conventional product near the boundary between the window frame 21 and the window glass 22. Here, a gap 23 has occurred between the mop cover 1 and the window glass 22. Even if the mop handle 17 is pressed hard, this gap does not disappear, and the gap remains uncleaned.

[0033] On the other hand, (b) shows an example in which the mop cover of the present invention is used. In this figure, there are no gaps 23 as seen in (a), meaning that every corner of the window glass can be cleaned without missing any spots.

[0034] When actually cleaning a window using the mop cover of the present invention and a conventional product, it was found that with the conventional product, areas near the window frame were not cleaned sufficiently, but with the product of the present invention, such insufficient cleaning was not observed. Also, with the product of the present invention, the handle is firmly fixed to the mop cover, so the handle does not wobble during use, and the window cleaning work proceeded extremely efficiently.

[0035] Although the present invention has been specifically described as relating to a window mop, it can also be used for items similar to window mops. Specific examples of items that can be used include floor mops for cleaning floors and wall mops for cleaning walls.

[0036] The present invention is not limited to the above-described embodiment. In other words, it goes without saying that the present invention encompasses design changes, including various modifications and alterations that would be conceivable to a person of ordinary skill in the art, without departing from the spirit of the present invention. Examples of such modifications include, as disclosed in Patent Document 1, fastening a portion of the mop cover opening, or providing a structure (such as a ring) for locking the head portion inside the mop cover. Furthermore, the first closure means may not have a second fastening line, and the closure means may be a hook-and-loop fastener, but may also be a string, button, or the like. The closure means may have first and second hook-and-loop fasteners on the same side in the width direction. [Explanation of symbols]
